This evening I attached the tank attach doublers and angles to the inboard ribs of the left and right tanks.

I did the left tank riveting solo and it came out alright. However it was pretty slow, so I asked Kerin to help drive the rivets for the right tank.

The right tank came out even better I think. Kerin did a great job on the rivet gun.

And the shop heads look great. I'm gonna seal over all these heads and start putting fillets around the ribs tomorrow.
